To all whom it may concern Be it known that 1, PETER KETELSEN, a

subject of the Emperor of Germany, but

{shock forming machines, and it proposes a machine which may be connected to the binder to travel therewith and to which the sheaves are passed as they are delivered from the binder.

The improved na'chine comprises a nuin- .ber of instruinent'alities, all correlated toward the end of efficiently producing and deliver-' ing shocksof regular contour, in which the sheaves are automatically and securely bound together. j Stated generally, these ins'tr'umentalities comprise a sheaf conveyer or transferring mechanism which takes the .she'a-ves as they aie delivered from the binder, a shock forming mechanism-to which the sheaves are passed from the transferring mechanism and by which they are arranged in a well formed shock having a definite number of sheaves, a shock binding mechanism by means of which the sheaves, upon completion of the operation of the shock forming mechanism, are bound and tied, and

a shock delivering mechanism by means of which, after the operation of the shock forming and binding mechanisms, 'the tinishedf'shock is delivered from the machine.

In addition to the mechanisms above specifled, the invention comprehends means for corirlating'the action of tllGlllQChtlDlSIXlS so that the operations may be performed with certainty and reliability and in definitely timed sequence.

' The objects of the invention, generally stated are to produce a completely finished shock by a series of automatically performed operations and by a machine which requires relatively little power for its operation and in which, considering the number and char acter of the operations involved, mechanism of comparatively simple nature is employed.

Qthef objects and advantages will appear as the description proceeds.

T he shook forming mechanism and its appurtenances.The shock forming mechanism includes essentially an upright casing 23 which is open at its upper and lower ends and is preferably in the form of a truncated cone, and an internal sheaf disposing mechanism, designated generally by the numeral 24, which is in coaction with'the casing 23 to arrange a determined number of sheaves in orderly fashion in a compact and symmetrical group. The sheaf disposing me'chanism is shown in detail in Figs. 13 and 14, and includes a cylindrical core 25 having associated therewith a'number of disposing arms 26. In the normal operation of the shock forming mechanism, the core 25 is disposed within the casing 23 with the arms 26 projecting horizontally and radially therefrom, and said core and therewith, said arms, are intermittently rotated. The arms 26 are arranged in vertical rows and afiyl suitable number of said arms may makeup a row. Thus, in the embodiment shown, there are three arm in each vertical row. The number of rows of arms 26 wil1 depend upon the number of sheaves which will constitute a shock. The drawings assume a shock composed of ten sheaves, and for this reason there are ten vertical rows ofarm-s 26. In

the operation of the shock forming mechanism, the sheaves, as they are successively delivered into the casing '23-from the sheaf conveying and transferring mechanism, en-

gage between adjacent rowsof arms 26, and

after each sheaf has thus been positioned between a pair of ad acent rows of said arms, the core 25, and therewith the'arms,

are rotated for a fraction of arevolution to present the next sheaf-receivin space to the next sheaf which i'sfed into tie casing 23. The core 25, in addition to its rotatingmovement, has also axial movements, upwardly and downwardly, ,and during the upward axial movement of said'core, the arms 26 are retractcd.- The axial movements of the core 25 are not concerned with'theformation of the shock, but rather with the delivery of the shock, and for this reason are-simply adverted to at the present time, their detailed explanation being reserved for a later portion of the description.

The rotation of the core 25 may be con-' veniently effected from the traction wheel 4 by suitable reducing gearing. Thu s, the hub of said v traction wheel is connected by sprocket gearing 27 to ahorizontal shaft 28 on the same side ofthe-machine as the tractionwhee1-4yan'd the shaft 28 is connected by sprocket gearing 29 to a horizontal shaft 30, which issupported on the top plate of ,the tower 2. The shaft 30 effects tne rota.-

tion of the core 25, and for this purpose said shaft is provided with a worm 31 which engages a worm wheel 32 on the upperpo'r'tion of the core 25. The worm wheel 32 is ke ed upon the core 25 andhas' an extended ub portion 32 by means of which it issuppor'ted on a bearing plate 33 which is' secured at the top of the tower 2. The worm wheel 32 also furnishes support for the core 25 in the lowermost position thereof,'said core for this purpose bein provided with a suitably located circumscri ing ring 34 which-, in the normal operation of the shock forming mechanism, rests upon the upper face of the Worm wheel 32. The casing 23 has at one side thereof a vertically disposed sheaf-re ceiving extension 35, which, in effect, forms a continuation of the casing 8, the discharge end of the latter being fitted. directly against or within said extension. f The shaft 30 is, as "above stated, intermittently driven from the traction-wheel 4, vand for this purpose, the sprocket 29,- which forms a part of the gearing 29 betwe'en the shafts 28 and 30, is loose on'the shaft 30 and is a ternately connected and disconnected therefrom by a suitable means. This means may conveniently be in the nature of a pawl and ratchet clutch, designated generally by the numeral 36, and of-a construction such as is shown in Figs. 10.to 12. The clutch 36 29 aforesaid is mounted, being loose on the shaft 30. The part 37 has an internal arrangement of notches 39,. and the part 38 has, internally pivoted therein, a lever 40 having apawl-like extension 41 forengage- 'ment in the'notches 39. The lever 40 is actl l ated by a suitable spring-42 secured within the part 38- to engage its extension 41 with the notches 39, andv isjprovided with an army.

43 which projects through a slot 44 in'the' annular wall of the part 38 for engagement by a part which is effective to move said lever inwardly against the tension of the spring 42 and thereby disengage-the 'exten sion 41 from the notches 39 and'permit the" sprocket 29 and therewith the clutch part 37 to run free of the shaft-30.

The above described relations of the clutch parts37 and 38 are varied by mechanism which, in one operation. is actuated by the sheaf in co ning through the extension 35. A simple arid preferred form of such mecl1awhich commounted at and a Y- nism isshown in the drawings, prises a'vertical rock shaft 45 one side of the extension 35,

shaped'lever 46 pivoted to the top bf thetower 2. The shaft 45 has at its lower end an arm 47 which works through alining horizontal-slots 48 in the adjacent walls of the extension 35, and the casing 8, and pro ects across the extension 35. The shaft 45 has git-its upper end an arm 49 to which is connected a spring 50 for holding said'shaft in f lever 40; and the arm 46 has at its end a finger fti for engagement in any one of a series of notches 52 in anotch ring 53, which is secured to the wornr wheel 32 to turn therewith, and withthe core 25. The lever 46 is connected .to a spring-54, the office of 46" lS";ll1 the path of the pawl-arm 43, and the: finger 46 will engage in an adjacent which is to'rnove said lever whereby, its arm notch .52., The pin 51 operates the lever 46 against the; tBIl'SlOII of the spring 54. Fig.5 shows't-he lever-46in such'a position that the. fingers 46., ofits arm 46-is 611'.

: ga'ged in a notch 52, When this relation spring 54, and thereby moves the arm 46 When this relationobtains the spring 42' therewith the. arm

the papd'rarm iifngages aga obtains the sprocket 29 runs. free of the shaft 30, and the latter'is consequently idle.

However, when a sheaf passes through the extension 35' it engages the'arm 47 of the shaft 46, andthereby rocks said shaft against the tension of the spring50, with the result that the pin 51, engaging. against the on the arm 46 of the lever 46,- rocks the lever 46 against the tension of. its

out of engagement with the pawl-arm 43, and-the fingers gagement with the notch 52 ofthe ring 53..

moves the pawl 'lev.'er=-40,' to the position shown in Fig. 11, in which position its extension 41 engages in an adjacent notch 39 and thereby connects the clutch part'38 for rotation with he clutch part '37. i Thereupon the shaft 30'is'rotated by the sprocket wheel 29*. When the sheaf which, by thus. engaging the arm 47 has produced the'operations referred to, passes by'said arm,.the spring 50 returns the "rock shaft 45, and- 47, to normal position. The lever .46, however,

51 by virtue of the engagement-of the finger 46 against the'periphery of thenotch ring 53, until such time as in said'ring comes adjacent 'sa1d finger, and the spring-.54 resets the lever --46,-

is-held' in the position to which it has been moved by the'pin moved from thepositi'on ofFig. .11, into the gosltionof Fig. 10-,yin which its extension 41 isengages the notches 39. At such time, the sprocket wheel 29 runs free of the'shaft 30 and the latter is idle. Each successive sheaf acts throughthe intermediary of thearm 47 and shaft 45 to operate the'lever 46 in the mannerstated. "The notches 52,

which provide for the resetting of the lever. 46, of course control the disconnection of I the shaft 30 from. the sprocket wheel 29,

such disconnection taking place each time that an empty sheaf-receiving space between adjacent-sheaf disposing arms. 26 is presented in line with the extension 35. It i is, of course, apparent that the number of notches 52 must correspond to the number of sheaf-receiving spaces-between-the sheaf disposing arms 26,"which, in the present instance, is ten. To move a sheaf from the.

extension 35 into thesh'eaf receiving space between adjacent arms: 26 presented to said extension, the following mechanism' is preferably'employed. On the side of said extension, adjacent thefront of the machine, there is mounted'a vertical shaft 55 having at suitableintervals thereon crank arms 56, which form-pivots for the sheaf packers 57-, of which three are employed in the instance disclosed. The packers 57 work through slots 58 in the adjacent wall of the extension 35, the crank arms 56 and at their forward ends pivoted to arms 59 on a suitably supported vertical rock shaft 60. The shaft 55. may be conveniently driven from the shaft 30 by suitable transmission gearing,

the numeral 61. Each operation of the shaft 30 thus not only effects the partial ro-' tation of the core 25, but it also effects a suitable number ofrevolutions of theshaft 55, asa consequence of which the packers 57 are alternately advanced and retracted to efi'ect the movement of a sheafbetween adjacent sheaf disposing arms 36. Figs. 25, 26 and-27 show the-sheaf packers 57 in detail. 35 gradually and that the wall in which the slots 58 are provided is somewhat inclined. In view' of this, thepackers 57 must be set at different angles with reference .to the arms 59, to which they are pivoted at" their forward ends, in order that 'they' mg all be completely retracted from the e ension '35 and may thus not interferewwith the movement of a sheaf intosaid' extension from the eas- 57, and

As above stated, the shock forming mech-v vanism has a'capacity for ten sheaves and when ten sheaves have been fed into the casing in the manner stated, so that all the {spaces between adjacent rows of arms 26 above described, the operation of the instru- .lnatically controlled clutch 6 5," of suitable so I similar to the pawland ratchet clutch 36 and in definite sequence or i are taken up, the other instrumentalit-ies of the machine come into action automatically relation.

Except for the shock forming mechanism mentalities of the machine is controlled directly or indirectly, as the case may be, from atransverse shaft 63 which is driven at intervals by gearing 64 from the traction wheel 4. The gearing 64-includes an auto construction, for instan'ce,' being exactly shown in Figs. 10, '11 and 12 andfabove described the sprocket 6459f, said and hi! wh h h s a flfifiiis notatedg hlnzzvre,

The engagement and disengagement of for example, by the following organization at elements; At the rear side of the extension 35 is 'pivotally mounted an arm 66 and ()7 which projects through a slot68 in the adjacent wall of the casing 23 and has its butt end fashioned to engage a pin on said arm. As the tenth sheaf, z. e. the one which completes the shock, is shock forming mechanism, the first sheaf, thus introducedinto said mechanism is being ;moved in line with the extension 35' and in such movement engages the lever 67. and

the arrows in Fig. 6, thereby causing said lever to move the arm 66in an opposite direction. The arm 66 has connectedthere- .to one'e-nd offa substantially'L-shaped member 68, at the angle of whih a resetting spring 69 is connected. The horizontal portion of the L-shaped member projects toward is connected to a bell crank lever 70, which in turn 'is connected by means of a linl 71 with a horizontal slide 72. The slide 72has its outer end suitably fashioned to engage connection of the members of said clutch in the manner already explained. The movement of the lever 67 by the sheafpassing adacent thereto in .the mannerv above ex- .f devices described, tocausethe disengagement of the slide 72- from the arm 65*, and

The slide 72 is provided with a collar 73 which, after said slide has been manner above explained, is engaged b a pivotally mounted detent 74, the latter t ns holding the slide 72 retracted'a'gainst the tension of the spring 69.

General consideration of the subsequent operations.-Operations subsequentto the formation of a shock are concerned with the of the finished binding and discharging shock." The casing 28 but its conical wall includes in its nlakeup automatically controlled displaceable parts or gates. In the delivery of the shock-the first action is to raise the sheafdisposing mechanism 24gand at the same time to re tract the sheaf disposing. arms-26. This operation frees the shock from the of the sheaf disposgates of the casing 23 position. Thereafter, the conveyer which forms the base of the casing 23and upon which the finishedshock will be supported is operated to carry now open gates of the casing 23 and to discharge the same through the rearend of the machine. 'The binding of the shock proceeds continuously with the shock forming operation; and during the raising movement of the sheaf'disposing -mechanism,;the binding operation is completed by a suitable knot tying and cord cutting device. Thereafter,

- the binding mechanlsm aotsin preparation forthe shock next to be formed When the finished shock has been delivered by the conveyer, the movement of theconveyer is arrested; the sheaf disposing mechanism returns toits position within the casing 23, or gates of the casing 23 "are .mov'ed to closed position, all

The rod 87 is formed at a suitable point with a slot 88 and the rack bars 83 are connected by a -pin 89 which passes through the. slot 88. 'The slot 88 is of subs ntially greater depth thanthe slot 85.

- the uppermost tielgjhhe extremities of said arms will, whenthe arms are retracted, be

substantially flush with the surface of core 25, and hence, in alinement' with the openings 79. Adjac'ent the openings 79 fand slots 84, in which the rack bars 83 work, are

of substantially greater depth than said rack bars. During the raising of the sheaf disposing mechanism, the rack bars; are first moved to the 'upper'end of the slots 84 and with relationto the core Thereafter, when the rack bars have engaged the upper ends of the slots 84, in their further upward movement, they, will carry the core 25 there with, so as to retract the core fromthe finished shock. It. is preferred to employ positive means for holding the core 25 against upward movement during themovement of the rack bars 83 toward the upper end of the slots 84, and in case the weight of said core should not be suflicient for this purpose.

,The means for positively holding the core 25 against upward movement during the period referred to preferably and conveniently comprises a pair of core detents 91, '(Figs. 1, 5, and 13) which are pivotally mounted, for example, on the upper faceof the worm wheel 32, in line with the slots 84. The de- 7 tents areprovided adjacent their lower ends with shoulders 92 which, when said detents are drawn inwardly engage the ring 34 which is carried by the core 25 and thereby positively arrest the upward movement of said core. At their upper ends the detents 91 are provided with noses 93, thefaces of which are inclined. \Vhen the movement of the rack bars 83 is first started, the arms 26 will carry the core therewith for a. very slight distance, only sufficient to bring the slots 84L- into line with the noses 93. There- Zup'on the springs 9%, which connect said detents, will move the detents inwardly, the noses 93 then entering the slots 84.;as shown by dotted linesin Fig. 13, and the shoulders 92 engaging overthe ring 34. The upward movement of the'core is thus positivel-y arrested, while the rack bars 83 move toward the upper ends of the slots 84. Ultimately, the upper ends of said rack bars will engage the adjacent inclined faces of the noses -93 and'will thereby move the detents.

The gear train thus supported, as shown more part cularly in detailinFigs. 14 and ;17, OOIDPIISGS horizontal concentric crown posite V irections by a train of gearing to be 7 hereafter described, and the inner crown ion gear 97, of course, rotates therewith. The

inner crown gear 97is in mesh with and rotates a spur, wheel 98. The spur wheel-98 drives a horizontal shaft 99 through miter" gearing 100, and theshaft 99, throit-zh similar miter gearing 101 at the ends thereof, drives a pair-of parallel shafts 102, each of which carries a pinion 103 for engagement with an adjacent rack bar 83. It is apparentthatif the crown gear 96' be turned clock; wise, the rack bars 83, and ultimately there with the core 25, will be raised, and if said crown gear be turned. counter-clockwise, the rack bars 83 and itherewith the core'25' will be lowered. Asshownin Fig. 14, th'egearto act at 'suitable,-times in changing the 1:0-

tation of the crown wheel 96 from clockwise "to counter-clockwise, and vice versa. Such gearing is preferably of. the following oranizatlon, as-hest'shown in Fig. 3. Above I the shaft 63 there is arranged a horizontal I shaft, 104 which is, driven alternately in oppositedirections from the shaft 63. Sprocket gearing 105' is employed to drive the shaft 104 in-the same direction as the shaft 63,-

with the pinion gearing 106." The movements of the member 107 are effected by a shifting lever 108, pivotally supported at its *upper end and in turn controlled by a cam wheel 109 on the cam shaft 77.. The lever 108 is provided with an intermediate frame nwhichthe cam wheel 109 is arranged, and said cam-wheel has contiguous semi-circular formations on its oppositefaces which alternately engage the opposite sides of the frame portion of the lever 108 and thus move said lever in opposite directions to vary the relation of the clutch member 107.

Theshaft 104 is used to drive a horizontal shaft 110, which is conveniently located near the upper end of the tower 2, chain and sprocketg'earing 111 being'employed as operative iconnections betwe en said shafts. The shaft 110, in turn,- serves to drive the crown gear'96, and thereby the gear train for raising and lowerin the shock disposing j mechanism, the connections for this purpose comprising a pinion 112 which is in mesh with the crown gear 96 and chain and sprocket earing 113. between said pinion andthe's aft 110. The shaft 110 is loose withj-relatio'n to the sprocket 111 of the "gearing 111, and is automatically put in operative and inoperative relation ,to said sprocket. For thisjpurpose the sprocket 111 has a clutch face at one side thereof, which coactswith a clutch nember 114 slidably keyed on the shaft 110. The clutch member 114 is controlled by a shifting lever 115 which islpivotally mounted at its lower endv and has an interme iate frame formedasa part-thereof.- Y The lever 115 is in turn operated by a cam. 116 mounted on the shaft mediatel-y after 77 and disposed in the frame of said lever. The engagement ofthev clutch member 114 with the sprocket 111-is'effected almost ime commencement of the rotation of the shaft 63,- and is disestablished very shortly before the rotation of the shaft 63 is arrested. Forthis reason the cam 116 hasa cam formation at one side thereof of relatively long extent, Which establishes the engagement of the clutch member 114 with the sprocket 111*, and a mere cam pointat the other side thereof which effects the disengagement of the member 114 from the sprocket 111 and is suitably located with reference to the cam formation first mentloned. The reason that the shaft 110 is driven'by means of clutch connections from the sprocket 111 is to enable said shaft to be disconnected from said sprocket during the operationof the shock forming mechanism, whereby it will simply rotate idly consequent to the rotation of the crown gear 96 with the worm wheel 32, from which said crown gear and the associated gear train have support, as above stated. At this point, it may be noted that the cam shaft 77 has but a single revolution to control all operations subsequent to the shockforming operation. For this reason, the gearing 78 which drives said shaft 77 from the shaft 63 is of speed-reducing character. This gearing may be of any suitable construction, but as shown in Fig. 3, it comprehends a number of inter-related chain and sprocket gears, of which the first sprocket 78 is nected sprockets 78 is, with convenience,

loosely mounted on the shaft 104 and the other pair of connected sprockets 7 8 is similarly mounted on the shaft 63.

Discharging the shoals-Opening and closing the casing 0 f the shock forming mechanz'sna-Asabove stated, the casing 23 includes displaceable wall parts orgates.

These are designated by the numerals 117 and 118 and are shown more particularly in Figs. 4 and 5. As a matter of convenience, the gate 117 is slidably mounted and is of curved form, its contour and sliding path following the annular outline of the stationary portion of the casing 23, which stationary portion is provided at its upper and lower ends with guide flanges 119 (Fig. 3) between which the gate 117 is held. The gate 118 adjoins the extension and may be conveniently hinged to awall of said extension.- During the upward movement of the sheaf disposing mechanism, as above explained, the gates 117 and 118 are opened; that is to say, the gate 117 is retracted and the gate 118 is swung outwardly on lts hinge joints; and during the downward movement .of the sheaf disposing mechanism, the gates 117 and 118 are closed; that is to say, the gate 117 is projected and the gate 118 is swung inwardly on its hinge joints until its of the gates 117 and 118 correspond to the respective upward and downward axial movements of the shed dlSPOSlElg mecha
